In my opinion I think this card should have been "Summon a 1/2 Poisonous Spider with Charge", a worst version of Assassinate in most cases but you can sometimes buff it to survive another turn for potential 2 hard removals

I think people are underestimating this card's potential. According to Team 5, they had this card at 4 mana but it was a bit too efficient. Two Poisonous 1/2's demand removal and are always a threat. I think people are gonna be surprised by this card.

This is a waste of five mana, your opponent could easily play primordial drake, dragonfire potion, hellfire, etc. The fact that thease could also be taken out by pretty muck any small attack minion also shows that for this to increase the chances to see play (though I still doubt it) would to either give thease spiders higher stats, or lower the cost, or both.

You get two tiny minions for the price of 5 mana, This card won't save you when you're facing aggro due to lacking taunt, this card won't help you gain control due to the spiders lacking enough health to resist Aoe.
